Prosessi polyolefiinien valmistamiseksi

摘要

The present invention relates to a process for producing polyolefms wherein a feedstock comprising n-olefin or a mixture of n-olefins is dimerized in the pres- ence of a solid acidic catalyst by passing the feedstock to a catalytic distillation apparatus comprising either a) a combination of a distillation column and a reactor comprising at least one catalyst bed, or b) a distillation column connected to one or more side reactors comprising at least one catalyst layer, recovering the unre- acted n-olefin from the distillation column or the combination of the distillation column and the reactor at the upper part thereof as a side-stream to be combined with the feedstock, and the reaction product from the dimerization is hydrogen- ated.
